| Summary: | This work presents a framework for the introduction of reciprocal dual polarization-plane rotators in waveguide technology. This concept is presented using rotational and longitudinal unit cells (rotational corrugations), stating rigorously the geometrical constraints required for its implementation. The devices have been studied from both a linear and a circular polarization modal perspective, using a mode-matching technique for rotationally symmetric modes and dispersion diagrams. Furthermore, various devices that use the proposed scheme have been designed to show the operation principle. A prototype has been built using additive manufacturing as a proof of concept. It has been measured using dedicated ortho-mode transducers (OMTs) for extracting the different involved signals and fully characterizing their performance. |
